You are playing a game in which you roll 2 dice. If the sum of the two numbers showing is greater than or equal to 10, you win. What is the probability that you win the first three times you play?
"Roll 2 dice, if the sum of the 2 numbers > or equal to 10 you win"
So the dices must be
5 5
5 6
6 6
6 4
4 6
That's 5 possibilities out of 30 I.e. 1/6
But If you play first three times "I.e. rolling 2 dice 3 times"
you may get:
5 5
6 6
5 4 etc..
3*6=18 possibilities, you could have any of the 5 possibilities above which you win
so 5/18
